Preheat your oven to 400°F (200°C) and prepare a baking sheet by lining it with parchment paper to prevent sticking.
In a medium-sized skillet, heat the olive oil over medium heat. Add the removed sausage meat, using a wooden spoon to break it into smaller pieces. Cook for about 5 to 7 minutes, stirring frequently, until the sausage is browned and no longer pink inside.
In a mixing bowl, whisk together the large eggs, a pinch of salt, and black pepper until smooth. Pour this egg mixture into the skillet with the cooked sausage. Add the chopped spinach and cook while stirring constantly until the eggs are fully scrambled and set, about 3-4 minutes. Remove the skillet from heat and fold in the shredded cheddar cheese until it melts and combines with the mixture.
On a lightly floured surface, roll out the thawed puff pastry sheets until they are smooth. Cut each sheet into 4 equal squares, yielding a total of 8 squares.
Take a spoonful of the sausage and egg mixture and place it in the center of each pastry square, being careful not to overfill.
Gently fold the four corners of each pastry square over the filling to create a sealed roll. Ensure that the edges are pinched tightly to prevent any leakage during baking.
In a small bowl, beat the additional egg. Brush this egg wash over the tops of the rolls using a pastry brush, which will give them a beautiful, glossy finish when baked.
Arrange the prepared rolls on the lined baking sheet, leaving some space between each one. Bake in the preheated oven for 15 to 20 minutes, or until they are golden brown and puffed up beautifully.
Once baked, allow the rolls to cool on the baking sheet for a few minutes before transferring them to a wire rack or serving plate.
Notes
Arrange the breakfast rolls on a decorative platter alongside fresh fruit and serve with hot sauce for dipping.
